OIL AND GAS BURNER.

To all whom it may concern:

Be it known that I, SAMUEL GRUNDY Fons'r, a citizen of the United States, residing in the city of Toronto, county of York, Province of Ontario, Canada, have invented certain new and useful improve ments in Gil and Gas Burners, of which the following is a specification.

My invention relates to improvements in oil and gas burners, and the objects of my invention are firstly, to construct a device of the class described which will be simple in construction, and easily taken apart to permit the same to be cleaned when necessary, and the component parts of which can be assembled without the employment of screws or bolts and the like; secondly, to

provide a device which while cheap to manufacture is yet durable and eflicient; thirdly, to construct a device of this class with an inner annular chamber so as to permit gas to pass thereinto from the generator to superheat a quantity of the gas, so to speak so that this superheated gas will raise the temperature of the mixing air and gas within the flue of the device high enough to consume any smoke that may be in the flue, and fourthly, to design a device of this class which can be used to burn ordinary illuminating or heating .gas, and the preferred construction of my device will be hereinafter particularly set forth and what I claim as new will be pointed out in the claims.

Figure 1 is a perspective view of my preferred form of device, and Fig. 2 is a vertical central section through the same, showing the device mounted in a suitable fire box which is also shown in section.

in the drawings :A is any suitable priming basin, provided with a threaded hub 13 through which screws the threaded lower end of the feed pipe C. The said feed pipe is suitably coupled to any suitable coupling D which leads to a source of fuel supply, not shown. The said priming basin is provided with a plurality of lugs E, preferably notched as shown at F to support the base member G of the flue H. The inner corner I of said base member G is preferably chamfered as shown, so as to permit the air to readily pass up 1nto said fine. The top edge J of the priming basin A is spaced below the bottom of the base member G so as to provide a passage-way wfor the air. The threaded hub B is pref- Specification of Letters Patent.

erably provided with a plurality of air holes K. Resting upon the base member G is the upper member L of the flue H. The inner lower edge of the upper member L is preferably chamfered as shown at 2 and rests upon the outer upper chamfered edge 3 of the base member Gr. Depending below the upper member L are a plurality of lugs at which overlap portion of the base member Gr. Tile construction just described is that which 1 preferably use to support the upper member L in proper relationship to the base member G. As illustrated in the drawings, the flue H is preferably tapered so that the upper end thereof is of less diameter than the base of the flue, to assist in the creating of a draft therethrough. Carried by the upper end of the feed pipe C is a sleeve 5 which surrounds said feed pipe. The in ternal bore of said sleeve is greater than the external diameter of said feed pipe, thereby providing an annular chamber 6. The said sleeve is preferably provided with a conical base 7, and resting upon said base and housing the said sleeve 5 is the generator 8. The said generator is preferably integrally provided with a plurality of spacing lugs 9 which are designed to prevent any undue lateral displacement of the said generator in respect of the sleeve 5.

As is usual in a device of this class, the priming basin is utilized to initially gen erate heat to heat the generator and other parts of the device. lVhen the device is first started, the liquid oil passes through the hole 10 formed in the plugged upper end 11 of the feed pipe C, and flows over the top and down the sides of the sleeve As the device becomes thoroughly heated, gas is formed within the pipe C and escapes through the hole 10 into the generator 8, and the same escapes from said generator at its lower end through the passage ways 12 formed in the inner lower edge of the base of the generator. As the gas escapes through said passage-ways into the flue, it mixes with the air passing into said flue through the air openings described, and the mixture is ultimately consumed.

The bore of the lower portion 13 of the generator 8 is of greater diameter than the rest of the bore of the generator, thus providing an expansion chamber at the base of said generator, thus permitting 1 of the rapid escape of the generated gas from the upper portion of said generator. The passage-ways 12 are quite small, and the result is that the gas in the said expansion chamber shall be raised to the desired temperature by the time it escapes through the said passage-ways.

Formed in the sides of the sleeve 5 are one or more holes 14, positioned within the lower portion 13 of the said generator, and the function performed by said holes is to permit gas to escape from the said'expansion chamber into the annular chamber 6. This gas naturally becomes ignited within the said annular chamber, and so assists in vaporizing the oil in the feed-pipe C. The

burning gas within said annular chamber 6 can only escape therefrom through the opening 15 formed in the conical base 7, and it naturally follows that as a result of the commingling of the burning gases from the said chamber 6, with the burning gases in the flue H, the temperature of the air and gases within the said flue will be raised high enough to consume any smoke that may result from the combustion of the gas passing through the passageways 12.

The preferred shape of the base 7 facilitates the escape of gas from the expansion chamber formed in the lower portion 13 of the generator 8.

Ihe construction described particularly in respect of the feed pipe 0 and the threaded hub 13 enables me to adjust the position of the device in respect of the top of the stove, not shown.

In Fig. 2 I show my device mounted within the fire box 16 of any suitable stove. In order that my device operate properly, I must place a plate 17 around the base member G, and this plate should fit the fire box. Since the said plate rests against the flange 18 of the base member G. no draft can escape by said plate to impair the action of my device.

From my experiments I have found that I can use my device as a gas burner. That is to say, ordinary illuminating or heating gas can be piped to my burner and consumed therein.

l/Vhile I have described what I consider to be the best embodiment of my invention,
